T0 @ZZ whmn it may concern.'

Be it known that I, Ofr'ro W. MEissNnR, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Dump-Cars, of which thefollowing isa specification.

The invention relates to that class of dumpcars known as Rodgerballast-cars, and

`particularly to the construction and arrangement thereof by which suchcars may be made convertible and used either as a center dumpcar of theRodger type or as a platform-car, all of which will more fullyhereinafter appear.

The principal object of the invention `is to provide asimple,economical, and efiicient convertible dump-car.

The invention consists principally in a dump-car in which there arecombined a supporting-framework, a V-shaped hopper portion securedthereto and extending1 below the same lengthwise thereof and with itsapeX at or near the longitudinal center of the car and formed in twoportions-a lower V portion and an upper foldable portion-secured to thevsupporting-framework of the car above the same, so as to form a portionof the inclined sides of the V-shaped hopper when in one position and aportion of the flat part of a platform-car in a second position, andside boards pivotally secured to the framework of the car and adapted toform the sides of a dumping hopper-car or be folded outwardly anddownone inclined side, CZ, rigidly secured to the framework and theother side, e, pivotally secured thereto at f, so as to form adischarging-door. The upper portion of this hopper is made of twoswinging sections g and ZL, pivotally secured to thesupporting-framework of the car above the same, so as to swing upwardlyand outwardly to complete the inclined side of a t-shaped hopper when inone position-that shown to the right of the figureand to be laid in aflat plane and complete the flat portion of a platform-car when in asecond position, as shown to the left of the drawing.

Y Swinging side boards made in two foldable portions c' and fareprovided and pivotally secured together at 7c, being also pivotallysecured to the framework of the car above .the same at Z. Thesejoints,which form thepivotal connection between the foldable portions ofthe side boards, aremade in the form of crulejoints, 7 so as to permitsuch portions to be folded back upon one another or arranged incontinuous form, as desired. The side boards are so constructed andarranged that they may be 'raised to an upwardly-extending or verticalposition and are provided with recesses m to receive the upper edge ofthe swinging hopper-sections and hold the same in their inclinedposition. To lockA them in 'such position, they are provided with Vlinks71 and the foldable side boards with chain-hooks p and q, by which suchparts are secured together and Y sustained in the desired relation, soas to form a center-dump hopper-car. To permit the formation of aplatform-car, the foldable side boards are released from theirinterlocking engagement with the swinging hopper-seetions and the upperpart j folded back upon the lower part t', so as to permit its chainhookto engage a locking-link 7. A hook t is provided on the lower part ofthe supportingframework of the car and arranged to engage with aneyebolt u on such board and hold the parts in position, as shown to theleft of the figure.

To open and close the discharging-door of the hopper portion, the usualrock-shaft Q; and chain mechanism u are provided and adapted to beoperated in the usual manner, all of which is well known and understoodby those skilled in the art.

I claim- 1. In a convertible dump-car, the combination of asupporting-framework, a V-shaped hopper portion extending lengthwise ofand below the same with its apex at or near the longitudinal center ofthe car and formed in two portions-a lower V portion and an upperfoldable portion secured to the supportingframework of the car above thesame so as to form a portion of the inclined sides of the V- shapedhopper when in one position and a part of the fiat platform of the earin asecond position, and swinging side boards pivotally secured to theframework of the car and adapted to form the sides of a dumpinghopper-car or be swung outwardly and downwardly to permit the formationof a platform-car, substantially as described.

2. In a convertible dump-car, the combination of a supporting-framework,a V-shaped hopper portion extending lengthwise of the car and formed intwo portions-a lower portion secured to the framework of the carextending below the same and an upper portion formed of two swingingsections pivotally secured to the framework of the car above the same soas to complete the inclined sides of the V-shaped hopper in one positionand the flat portion of a platform-car in a second position, foldableside boards pivotally secured to the framework of the car and arrangedto be placed in a vertical position to receive the upper edges of theswinging hopper-sections when in one position and to be folded outwardlyand downwardly in a second position,

and means for securing the foldable side boards to the swinginghopper-sections to hold both of such parts in desired relation,substantially as described.

3. In a convertible dump-car, the combination of a'supporting-framework, a V-shaped hopper portion arranged lengthwisethereof and made in two parts, a lower V-shaped portion secured to theframework of the car and below the same, and an upper portion formed oftwo swinging sections pivotally secured to the framework of the carabove the same so as to complete the inclined sides of the V-shapedhopper in one position and the flat portion of a platform-ear when in asecond position, and swinging side boards made in two foldable portionspivotally secured to the framework of the car and having recessesarranged to support the free edges of the swinging hopper-sections inone position and be folded together and swung outwardly and downwardlyto permit the formation of a platform-car when in a second position,-and means for securing both portions of the foldable side boards to theswinging hopper-sections to sustain the parts in the desired relation,substantially as described.

4. In a convertible dump-car, the combination of a supporting-framework,a V-shaped hopper arranged lengthwise thereof and made in two portions-alower V portion having one fixed and one swinging section extendingbelow the supporting-frame and an upper portion formed of two swingingsections pivotally secured tothe framework of the car above the same soas to complete the inclined sides of the V-shaped hopper in one positionand the flat portion of a platform-car in a second position, swingingside boards made in two foldable portions pivotally secured to theframework of the car and having a recess in which the upper edges of theswinging hopper-sections rest, rule-joints forming the pivotalconnections of the swinging side boards and foldable portions, andlink-and-chain mechanism for holding the swinging side boards andhopper-sections in desired relation, substantially as described. 4
